HENRY W. LAMBERT, OF STOUGHTON, MASSACHUSETTS.

SHOE-JACK.

Specification of Letters Patent.

Patented Aug. 26,1913.

Application filed August 26, 1912. Serial No. 716,953.

To all whom it may concern:

Be it known that I, HENRY W. LAMBERT, of Stoughton, in the county of Norfolk and State of Massachusetts, have invented new and useful Improvements in Shoe Jacks, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof.

This invention has reference to improvements in shoe jacks, so called, used in the manufacture of shoes and particularly adapted to conveniently hold a lasted shoe during the tacking, tack drawing or inner seam trimming operations.

One object of the invention is to so construct a jack of this nature that the lasted shoe upper may be adequately supported during the tacking operation and that the last and the partially manufactured shoe can then be swung to a position convenient for the trimming of the inner seam and sustained against lateral movement in one direction while in such position.

Other objects of the invention willv appear from the following description.

The invention consists in such novel features of construction and combination of parts as shall hereinafter be more fully described and pointed out in the claims.

Figure 1, represents a side elevation of the improved ack, a shoe last being shown thereon. Fig. 2, represents a plan view of the same, the swinging of the last from one position to the other being indicated. Fig. 3, represents an end view of the same partly in section.

Similar reference characters designate corresponding parts throughout.

As shown in the drawings in its preferred form 5 indicates a substantial heavy base having at one end the hollow posts 6, 6 and along its central portion the slot 7. Inthe bores of posts 6, 6 are adjustably secured the vertical members 8, 8 of the support 9 which latter is bent to form the stop 10. In order to cushion said support 9 itis furnished with the rubber tube 11.

Slidable along the slot 7 is the bracket 12 which is secured against movement along said slot by any ordinary clamping device having the tightening nut 13 and said bracket 12 is furnished with the hollow posts 14 and 15 in the former of which is adjustably mounted the last pivot 16 while in the latter post 15 is adjustably secured the vertical sto-prod 17 having the tubular rubber covering 18.

This improved device is used as follows: The last A having thereon a partially constructed shoe is engaged with the last pivot 16 and the toe portion of said last is swung to the position shown in Fig. 2 with said toe port-ion sustained by the support 9 and bearing against the stop 10 which limits its movement in that direction. The tacking process may now be carried out as the last and its partially constructed shoe are firmly supported for that purpose. When it is desired to trim the inner seam of the shoe, or for any other purpose, the last A with its partially constructed shoe is swung to the position. indicated in dotted lines in Fig. 2 in which the side of the shoe bears against the vertical stop 17 which limits the movementof the shoe and the last in that direction. The adjustment of bracket 12 along slot 7 is for the purpose of adjusting the pivot 16 with reference to the support 9 and its stop 10 for lasts of various lengths while the vertical adjustment of the support 9 and the pivot 16 and stop 17 is to accommodate lasts of various heights as well as for the convenience of the operator and to facilitate his work.

Having thus described my invention I claim as new and desire to secure by Letters Patent.

l. A shoe jack of the nature. described comprising a base having at one end \a last toe support and stop, and a member adjustable along said base and having a last pivot and a last stop whereby a last mounted on said pivot may be limited in its swinging movement in two directions.

2. A shoe jack of the nature described comprisinga base, a vertically adjustable last toe support and stop located at one end of said base, and a member adjustable along said base relative to said toe support and having means for securing it to said memher, a last pivot carried by said member, and' a last stop carried by said member and positioned at a distance from said pivot. 3. A jack of thenature described comprising a base, having a longituollnally extending slot and a pair of tubular posts, a

supporting frame bent to form a stop at mounted in the other of said bracket posts, one end and having vertically extendmg substantially as described.

members adjustably secured in said osts 3 1 a bracket adjustable along said slot and liav- HENRY LAMBERI' ing clamping means and a pair of tubular Witnesses:

posts, a vertical last pivot mounted in one N. A. DAVIS,

of said bracket posts, and a vertical stop W. L. DUNBAR.
